The present invention provides a touch panel controller for controlling even a large touch panel with little EMI. An input device interface 150 may receive a coordinate input 350 from an input device. In one embodiment, the linac includes an electron gun for generating an electron beam, and a plurality of accelerating cavities which accelerates the electron beam by applying electromagnetic fields generated by a microwave source. The integration of the organic thin film transistor and the organic electroluminescent device can widen aperture ratio and increase process reliability. When disposed in the second spaced configuration, less conveyor track is necessary to hold and move a number of carriers through an inclined and declined portion of conveyor track, as well as a through a workstation resulting in less manufacturing and operating costs. The display device includes semiconductor layers formed on a substrate and having pseudo single crystal regions and a plurality of thin film transistor arranged in the inside of the pseudo single crystal regions.
